Specification of Letters Patent.

- Application filed June-26, 1906. Serial No. 323,504.

To all whom it may concern:

Be it known that 1, WILLIAM- T. DE WORTH, a citizen of the United States, residing at Bordentown, in the county of Burling ton and State of New Jersey, have invented a new and useful Hose-Clamp, of which the following is a specification.

' This invention relates to hose couplers and has for its object to provide means whereby a hose or other fluid conducting pipe may be secured to the discharge end of a faucet withni le or cou 1 r i further obj ec% is to provide an eXpansible sleeve having a clamping collar associated therewith and adapted to compress the walls of the sleeve thereby to clamp the hose in frictional engagement with the faucet.

A further object is to provide a threaded sleeve one end of which is tapered and rovided with a plurality of spaced longitu inal slots, the threadsat the op osite end of the sleeve being spaced inwardly to present a smooth bearing surface for engagement with a suitable tool when positionm the device on a hoseor other fluid conductmg pipe.

A still flirther object of the inventlon is to generally im rove this class of devices so as to increase t eir utility, durability, and efliciency as well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter'fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of theappended claims. I

I In the accompanying drawings forming a part of this s ecification: Figure l is a side elevation of a I ose constructed in accordance with my invention showing the same applied to a faucet. Fig. 2 is a longitudinal sectional view .of the saine. Fig. 3 is a detail pers ective view of the contractible sleeve detac ed. Fig. 4 is a similar view of the clamping collar, and, Fig. 5 is a longitudinal sectional view showing the coupling used for connecting two sections of hose.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The lmproved coupling is principally designed for-connecting a hose or similar fluid conducting i peto the discharge end of a faucet and )y way of illustration. is shown applied to a faucet of the ordinary construc-, tion in which 5 designates the faucet and 6 a portion of the hose.

The couplin consists of a contractible sleeve 7 the adjacent lon itudinal edges of which are spaced a art to orm a slot as indicated at 8 and t e exterior walls thereof threaded at 9 for the reception of a clamping collar 10. The threads 9 are spaced inwardly from one end of the sleeve to form an annular bearing surface 11 preferabl disposed in alinement with the threads 9 or engagement with-a wrench or similar tool when positioning the sleeve on the hose 6 so as to revent the sleeve from rotating when adusting the clam ing member or collar 10. The threaded wa s of the sleeve are inclined or tapered towards one end thereof and formed in said walls are a plurality of spaced recesses 12 which extend from the smooth bearing surface 11 and open through the reduced end of the-sleeve, as shown, so that when the clamping collar 10 is adjusted on the threaded end of said sleeve the walls of the latter will be compressed and clamped in engagement with the hose thus securing the hose in position on the faucet without the em loy'rnent of the usual threaded nip le.

using the device the end of the ose is ositione dcver the discharge-end 15 of the aucet and the collar 10 ad usted longitudinally of the sleeve thus clamping the hose in frictional engagement with the faucet and forming a water. tight union between the same. When the coupling is used for con-- necting two or more sections of hose the eX- tension 14 of the ni ple 16 is inserted in one end of the hose a ter which the sleeve is placed in position and the collar 10 adjusted in the manner before stated thereby preventin accidental withdrawal of said nipple.

Wh' e the coupling is principally designed for use on ordinary garden hose it is obvious that the same may be used with e ually ood results on steam, air or other fluid conucting pipes. I From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.

Havin thus described the invention what i formed from a sin le piece of metal and having its side Walls of uniform thickness throughout but tapered towards one end of the sleeve to form a truncated cone and provided with exterior threads which terminate short of the opposite end of said sleeve to form an annular collar having a smooth exterior surface disposed iii alinement with the threads and arranged flush therewith, the interior Walls of the sleeve being unobstructed throu hout their entire length to form a smooti bearing surface for engagement witha hose, there being a lon itudinally dis osed slot extending the entire length of the s eeve and intersecting the annular collar, and a lurality of spaced lon itudinal recesses ormed in the threaded wa ls of the sleeve on each side of the slot and extending from the inner end of the collar to and opening through the reduced end of the sleeve, the walls of said recesses being arranged parallel with each other and disposed at right angles to the transverse axis of the sleeve, one of said and having its exterior surface roughened,

the threads on the sleeve between the spaced recesses being continuous and unobstructed. In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
